Embodiment Construction

[0056] Such as image 3 As shown, the present invention is a model with new features, specifically a feature model for demand modeling and model conversion, and the feature model includes:

[0057] Ability feature, the capability feature includes a function layer, an operation layer, a presentation layer, and a service layer, wherein the service layer is located above the function layer, the operation layer, and the presentation layer, and the service feature of the service layer is composed of a function feature, used It is used to represent the abstract functions of the system to be built;

[0058] Quality characteristics, the quality characteristics include four hierarchical structures, which are NFR goals, NFR levels, implementation, relationship and environmental conditions, wherein NFR goals are the non-functional requirements that the application system should meet; NFR levels refer to a single implementation in the entire The level in the field reflects the satisfacti...

Abstract

The invention discloses a requirement modeling method based on a new characteristic model and a model transformation method. A model is established by the new characteristic model through a hierarchical structure of expansion of ability characteristics along with addition of a 'service layer' and a quality characteristic with addition of four hierarchical structures. Five types of conditions of the characteristic model are simplified to two types of conditions through introduction of a 'selectable set'. A requirement modeling technological process is designed according to the new characteristic model. A characteristic pattern is converted into a unified modeling language (UM) class pattern and a UML case using pattern. The requirement modeling method based on the new characteristic model is capable of greatly promoting reusability of software requirement assets and improving production efficiency and quality of software. The model transformation method is joined with the requirement modeling method based on the characteristic model and a UML pattern modeling method.

Description

technical field [0001] The invention relates to the technical field of requirement engineering, in particular to an application for requirement modeling and model conversion based on a new feature model. Background technique [0002] In recent years, with the development and progress of feature-oriented domain analysis technology (FODA), the requirement modeling method based on feature model has been accepted by more and more requirements engineering researchers, and has been widely used in software requirement analysis and File. The requirement modeling method based on the feature model takes the feature as the basic unit to capture the domain requirements, and the feature model as the way to organize the domain requirements. The feature model reflects the software requirements of the entire domain, which can effectively capture a set of relatively stable capability features and their relationships from user requirements, and show the commonality and variability of domain ...
